Module com.aoapps.servlet.subrequest

Package com.aoapps.servlet.subrequest

Class UnmodifiableCopyServletRequest

java.lang.Object

com.aoapps.servlet.subrequest.UnmodifiableCopyServletRequest

All Implemented Interfaces:

ServletRequest

Direct Known Subclasses:

UnmodifiableCopyHttpServletRequest

public class UnmodifiableCopyServletRequest
extends Object
implements ServletRequest

Achieves thread safety by making copies of most fields during constructor and being unmodifiable. This forms a base point for subrequests to diverge from.

Some methods have to read-through to the wrapped request, so it should not change state while this wrapper is in use. Synchronizes access to the wrapped request.
